extend_param

The last proportion parameters is redundant, since it is equal to 1 minus
the sum of all other proportion parameters. This function ats the last
proportion parameter back to the parameter matrix.

internal

Implements the truncated harmonic mean estimator (THAMES)
of the reciprocal marginal likelihood for uni- and multivariate mixture
models using posterior samples and unnormalized log posterior values via
reciprocal importance sampling.
